Today only, B&H is offering a rather nice deal on two of their 32 and 64GB SanDisk SDXC Extreme Class 10 SD cards. With maximum write speeds of 45MB/s, they’re a great option to have as either your main memory solution, or a back-up in bodies with dual card slots.
The SanDisk 64GB SDXC Extreme Class 10 Card is on sale for $50 — down from B&H’s already competitive price of $70 — while the SanDisk 32GB SDXC Extreme Class 10 Card is down to $25 from B&H’s usual $38.
Meant to stand up in the most extreme conditions, these two cards are waterproof for up to 72 hours in a meter of water (salt or fresh), temperature proof from -13 to 185°F (-25 to 85°C), shockproof up to 500Gs, and even immune to X-Rays for those times when you accidentally send it through the dreaded airport scanner.
From looking elsewhere online, this seems to be one of the best deal on either of these cards to date. As far as how extreme they really are, I can’t speak for them in every regard, but I’ve accidentally sent one of mine through the wash a few times (I swear they hide themselves in a pocket within my pocket) and that card is still cranking out images without missing a beat.
